Name: Schizachyrium scoparium - Bouteloua curtipendula Northern Grassland Alliance Reference: NatureServe Biotics 2019 Description: This dry and dry-mesic grassland alliance occurs in the northern tallgrass prairie region of the United States and possibly Canada. It can be moderately open and is dominated by midgrasses such as <i>Bouteloua curtipendula, Bouteloua gracilis, Hesperostipa spartea</i>, and <i>Schizachyrium scoparium</i>, with <i>Andropogon gerardii</i> and <i>Calamovilfa longifolia</i> occurring in some examples. Lichens and mosses often occur on bare soil and gravel. Occurrences of this alliance are on rocky, loamy south-facing slopes and on glacial outwash, glacial beaches, or other glacial features that have a high proportion of sand and gravel, such as kames and eskers. Soils are often Mollisols but not deep, and they contain fine to coarse gravel, sand, and often larger rocks. Soil moisture is typically low due to being well- to excessively drained. The lower nutrient levels, lower levels of organic matter, and lower water-retaining capacity influence the species composition and structure of this alliance.  Accession Code: urn:lsid:vegbank.org:commConcept:39229-{D06D6AB9-FF89-4788-966C-E8CC038B53FD} Plot-observations of this Community Concept: 0
